Default Home Audio quesiton.

What exactly is Bi-amping and Bi-Wiring. I just bought a new Speaker system and i noticed my speakers have 2 positive and negative terminals. Here is my set up:

pioneer vsx-1122-k

Polk speakers:
2xMonitor 70
2xMonitor 40

Will the sound be better if i bi-amp or bi-wire and which is best? Will 5.1 bi-amp sound better than 7.1? Lastly the owners manual says for bi-amping to connect the Surround Back/Zone2 to the higher terminals of the front speakers. Why would you connect surround out put to front speakers?
page 20.

maybe you could review bi-amp and bi-wireing on the show and explain how to set it up.

After wiring the speakers with the highs and lows of bi-amping, "Front Bi-Amp" must be selected from the System Setup Menu. This is on pages 21 and 80 of the Pioneer manual.

Heed the caution at the bottom of page 20 concerning the removal of the plates that are over the high and low terminals and that must be removed for bi-amping.

Make sure to follow a 5.1 speaker setup - Left Front, Center Front, Right Front, Left Rear, Right Rear and a single powered sub-woofer. The diagram on page 20 has two sub-woofers.

Use Patrick Norton's hint about the placing of a sub-woofer:
1) Place connected sub-woofer where a listener will be seated. That's usually in front of the TV.
2) While playing the sub-woofer, walk around the room.
3) The spot in the room where the sub-woofer is loudest is the spot where the sub-woofer will be placed.

A 5.1 setup with the speakers that you mention will sound very impressive. No need for 7 speakers or two sub-woofers unless there is a very large listening environment.

I don't see a need for the bi-wiring setup on page 20. either.

Good luck.

Default Bi-Wired

Bi-wiring is running two lengths of cable between the power amplifier and loudspeaker. This technique usually produces much better sound quality. The jumpers connecting the two pairs of binding posts must be removed. In a bi-wired system, the amplifier "see's" a higher impedance on the tweeter cable at lower frequencies, and a lower impedance at higher frequencies, The opposite is true in the woofer-half. This causes the signal to split up and reduces magnetic interactions in the cable, resulting in better sound. I use bi-wiring in my setup.

I set up speakers for rich people and have tried bi-amp and bi-wire on audiophile grade equipment with no noticable change in sound quality. If you check out AVS Forums most of those guys would tend to agree with me. You can bi-amp to improve quality but it involves external crossovers and can get very tricky. There is no harm in trying it anyway but that is my 2 cents.
